A TTORNE Y Umts STATES PATENT FRITZ ENssLE', oE RosELLE, NEW JERSEY.

REVERSIBLE ROTARY MOTOR.

To all 'whom tmay concern:

Be itknown that I, FRITZ ENssLE, a subject .of the Emperor of; Germany, resident of Roselle, county of linien, and State. of New Jersey, have invented certain new Yand usefulf Improvements in- Reversible Rotary Motors,1ofwhich theffollowing is aspeciication. V s

This invention relates to. improvements in rotary motors or engines 4adapted 5 to use fluids, gases or'compressed vair and whlch Vare reversible as to the. direction of. their -rotation;I f f y y'The principal object of theinvention is Vto provide a compact lform of motor which `may be operated in 'either direction, :and provided with two or moreinlets and asingle exhaust opening.l

provide a motor in which the impulsive 'efect of the current-used is received upon elements pivoted to the central cylinder in such mannerlas to turn'according tothe direction of rotation desired.A

These and other likes-objects are attained bythe novel construction* and combination of partslhereinafter described and shown in the accompanying drawings, forminga Inaterial'part of this specification, and V1n which,l l 1 Figure 1 isa partial side elevational and vertical sectional view taken on `line 1 -1 ofiifiaa`- Fig'. 2is'a-vertica`l sectional view taken on another plane on line 2-2 of Fig. l.

Fig. '3 vis a side" elevational view` of the motor completely assembled.

Fig. 4 is a fra ental sectional view taken on line 4-4 o Fig. 1, and

Fig. 5 is a fragmental side elevational and sectional view of the same.

Throughout the several drawings, the numeral 10 indicates the base from which rises standards 11 the same being integrally connected with the body 12, and having one lateral finished surface 14, to which is attached a cover plate 15, by means of bolts 16, and screws 17, the former passing through raised lugs 18, formed with the body of the casing the Cover having similar lugs 19, and a hub 20, formed to receive packing material 21, held by the nut 22, through which the shaft 23 passes,

The opposite end ,ofthe shaft is received body 12, while the .end extending'throughfrY the cover plate is tted with a drivingwheel 25 for obviousYK purposes. v

Vlhe casing contains a cylindrical boreI 28 having therein a rotatablyV mountedsolid which are held in v disk 29, the same being held tothe shaft 23,". yby the key 30. Circumjacentto the disk 29, are rings 33, between which apartition l31 is provided integral with one of the ringsj33,

by'V .means of circular plates 35,' which are -f clamped togetherl by means of throughbolts recessed upon thelrouter sides, as are the adjacent surfacesaof the cover 15 andbody 12, thereby reducingthe supericial area of the parts in contact...

^ The rings 33 vare recessed the recesses hav ing an arcuate formation .at their `ends and being disposed so `as to form pockets 88 1n staggered relation upon both sides of the partition 31, in which shaped rocker buckets 40, pivoted ,upon the bolts 36, and having centralhubs 41, movable in corresponding recesses 42 of the disk l29, the vbucket ends being formed to suit 7K5 'f operate segmental ifV the vcurvededges 38 of the recesses in the:-

rings 33, and the outer surfaces of the buckv ets formed with a curved profile 43; y

Extending from near the top ofthe casing 12, are angularly disposed hollow proports or passages opening into the casing f jections 45, containing and 48 respectively, and being separated Vlongitudinally into `equal parts by a'partitionwall 49j Revolu-` bly mounted in the upper portion of the projections are rotator] valves 50, adapted to control the port openings and divert the propelling medium through either of the ports 46 or 48, the air or gases enteringl through the openings 52 Vof the screw threaded projections 53 from aV supply source. v

The valves 50 are operatively engaged by the caps 54, the stems 55 of the valves being fitted with nuts 56 at one end, the other extending ends 57 being squared and having fitted to them crank levers 58, both of the levers being pivotally engaged by :alink 59, having near its centera in a slot 62, formed longitudinallyin a hand lever 63, pivoted on a ibolt lixed in a propin 60 operating y 'jection 65, formed with the casing l2, the lever having at its other end a handle (5G by means ot which it may be operated.

0n the opposite side of the lever G3, is an index tinger GS, indicating` the posit-ion of the valves as set to cause the motor to move forward, reverse, or remain stationary, the position of the tinger 68, being indicated upon a sector 70, supported by a bracket Tl, attached to the top ot' the casing l2.

Discharge or exhaust from the motor takes place through an extension 75, having a passage 76, terminating in a horizontal screw threaded projection 77, to which may be connected a pipe leading to the atmosplicre.

The operation of themotor is as follows: The valves being set as indicated in Fig. l, compressed air passes through, entering the inlets 525, passing` through the valves 50, and is diverted thereby to the lett side oie. the partition l1-vf), and pass through the openings Lt6, impinginy on the rear ot' the rocker euckets l0, causing them to move around the bore ot the casing and the ring to rotate, and by 'reason o't its engagement, with the dist: 2), actuate thc shatt 23, and whatever may be attached to it.

rlie rocker buckets are uniformly disposed upon opposite sides of the disk, in staggered or ott-set relation, and by reason ot the two inlets. at least one of the buckets is always inv position to receive an impulse thereby avoiding dead centers and the like.

llfhen it is desired to reverse the motor the lever oscillated, thereby partially rotating the val ves, deliveringv current to the rocker buckets, causing` them to turn upon the holts, 36 in the opposite direction, so as to receive current unen their opposite sides. It will be obvious that when the lever titi, is vertical the valves will be closed, permitting no current to enter the interior of' the motor.

Having;- thus described my invention what 'goggles of this patent may be obtained for upon opposite I claim as new and desire to secure by Letters Patent, is:-

l. In a rotary motor, the combination with. a rigid hollow casing, a cover iitted thereto, and a shaft mounted lpartially in said casing and said cover, of a disk engaged with said shaft, annular plates on the sides oi said disk, clamping' elements engaging said plates to said disk, rings surrounding said disk through which said clamping elements pass, a partition between both rings integral with one of them, pockets 'formed in said rings in 'staggered relation sides ot said partition, a plurality ot rocker shaped buckets pivotally mounted in said pockets, inlet ports, coinn'lunicating' with said casing, valves controlling said ports whereby an entering` current may be diverted to either vside ot saidrports and caused to inipinge upon either end ot' said rocker buckets,A and means for operating said valves.

2. In a reversible rotary motor, the combination'withacasing'having a central. bore, a cover engaged therewith, and a shat't journaled in said cover and said casing, ot ay solid disk engaged on said sh att, a pair ot annular plates on said sha'tt at the sides ot said disk, rings surrounding said disk, pivot bolts connecting` said plates and saidrings, a partition between both rings integral with one oi" them, pockets formed inv said lrinejs in staggered relation upon opposite sii es otf said partition, a plurality of rocker buckets in said pockets, said buckets having a part operable in said pockets, one or more inlets to said casing, means formed in said inlets ve cents eaehg Yby addressing the Commissioner of mittente,
